Abstract (en)
[origin: WO2022121672A1] A positioning accuracy evaluation method and apparatus, which are used for implementing comprehensive evaluation of the positioning accuracy of a vehicle-mounted navigation device or system under a vehicle-mounted dynamic driving condition. The method comprises: determining a scenario where a positioning device to be tested (302) is located (201), and determining the positioning accuracy of said positioning device according to the scenario (202), wherein the scenario is related to the number of different satellite signals received by said positioning device (302) at the same moment. In this way, the positioning accuracy of a vehicle-mounted navigation device or system in multiple scenarios can be evaluated in a relatively objective and comprehensive fashion, such that the requirements for the high reliability and safety of vehicle-mounted navigation devices or systems in the field of the intelligent connected vehicles are met.
